Factors that Affect the Diameter of the Crater Produced by Dropping a Metal Ball Research Question What is the effect of increasing the dropping height of the metal ball on the diameter of the crater that is produced? Variables Independent Variable:
the height in which the ball will be dropped at 5cm, 10cm, 15cm, 20cm.
the height will be measured by a ruler (+/ 0.5mm)
Dependant Variable:
the diameter of the crater
measured by the ruler (+/ 0.5mm)
Control Variable
the substance inside the contain
mass of the metal ball: 57.8g (+/ 0.01g)
force applied to the ball when dropped
the amount of substance inside the container: 345.5g (+/ 0.01g) Materials 1 blue container
345.5g of sand
1 metal ball
1 ruler (+/ 0.5mm)
1 electronic balance (+/ 0.01g) Procedure 1. Place 345.5g (+/ 0.5g) of sand inside the blue container.
2. Use a ruler to measure 5 cm from the outside of the container and get another person to drop the ball from that height without applying any force.
3. Slowly extract the ball from the container trying not to change the size of the crater.
Then measure the diameter of the crater with a ruler.
4. Once recorded, flatten the sand and repeat steps 23 again two more times.
5. Repeat steps 24 for conditions at 10cm, 15cm, and 20cm.
6. Empty sand from container, rinse and return materials.
